Method of coujstterposing gasometers



P. T. BURTIS, OF CHICAGO, ILLINOIS.

METHOD OF COUNTERPOSING GASOIVIETERS.

Specification of Letters Patent No. 20,988, dated July 27, 1858.

To all cli/0m t may concern:

Be it known that I, P. T. BUR'rrs, of Chicago, in the county of Cook and State of Illinois, have .invented a new and Improved Method of Suspending Gasometers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this speciii cation, in which` Figure 1 is a vertical section of a telescope gasometer with my improvement applied. F ig. 2 is a plan of the same.

Similar letters of reference indicate corresponding parts in both figures.

This invention is applicable to telescopic gasometers or to gasometers in which the holder ,is single.

It consists in a certain arrangement of the chains connecting the counterbalance weights of the holder or any of .its sections, whereby any binding in the tank and uneven rising and falling, and the loss of gas and other bad consequences thereby caused are effectually prevented.

To enable others to make and use my invention, I will proceed to describe its practical application and operation.

The gasometer represented in the drawing is of the telescopic kind, with the holder in two sections, and has my invention applied to the lower section, which will be in many cases sufficient though itv may be applied to every section of a telescopic gas holder.

A is the tank; B, the lower section of the holder; C, the upper section of the same; D, D, grooved guide rollers attached to B, and C, to work on vertical guides E', E, on the columns E, E, which support the pulleys over which run the chains by which the lower section of the holder is suspended.

ci, a, are the chains usually employed to suspend the holder, each working over two pulleys and c, on )ne of the columns E, E, on the same side of the holder to which it (the chain) is attached and having attached a counterbalance weight d, which may be arranged to work within the column. These chains (of which there are an even number arranged at equal distances apart) are attached to the holder by rods a, a,

which are furnished with screw swivels L, 7b', by length.

e, e, are chains connecting each of the rods a', a', with the weight (l, on the opposite side which to adjust them to a proper of the gas-holder, the said chains passing over pulleys f, f, .in brackets g, (y, which are secured on top of the nearest columns, and from thence right over the top of the gasholder and over pulleys and c, arranged on the same axles with the pulleys and c, of the opposite column. The chains a, and e, are separately attached to their respective weights (Z, so as to be independent of each other. The chains c, c, are furnished wit-h screw swivels by which to adjust them to a uniform tension with a, a, and the portions of the said chains which cross each other consist of rods e, e. By the combination of the chains e, e, and a., a, the gasholder is connected at each point of suspension with two weights on diametrically opposite sides of it and each weight is connected with the gas-holder at two diametrically opposite points of the latter.

The chains having been adjusted so that a uniform tension is produced upon th-em all when the gasholder is level or even, all the counterbalance weights act alike each bearing its own proportion 4of the weight until therev is any tendency on the part of the holder, owing to its binding in its guides or from other cause to rise or descend unevenly when the chains a, and e, connected nearest to its highest point, are relieved of tension, and the whole weight of both of the counterbalance weights with which those chains are connected is thrown upon the opposite chains a, and c, that is to say, those connected nearest the lowest side of the holder, which tends to draw up the lowest Side while the highest side is left free to descend, so that the holder, if .it should get out of level at all, can get out but very little before it rights itself.

What I claim as my invention, and desire to secure by Letters Patent, is:

The arrangement of the chains c, c, in combination with the weights d, (Z, and chains c, a, substantially as herein described; whereby, when there is any tendency on the part of the holder, or the section thereof to which said weights are applied, to work unevenly, the highest side is relieved from the counterbalance weights and two of the said weights are brought wholly .into action on the lowest side, substantially as herein explained.
